Table 1: Chemicals of Concern and Associated Chemical Information. PACs Rev. 28, February 2016

Table 1 is an alphabetical list of the chemical substances, their Chemical Abstracts Service Registry Numbers (CASRNs)1, and pertinent physical constants. Future reviews will result in continuous updates to these data. There are also columns that provide the date of the original derivation of the PAC values, the date of the last technical review of the data used for deriving the PAC values, and the date of the last revision of the data used to derive the PAC values.

The information presented in this table is derived from various sources including:
